SPECIFIQATIOINformng par-tof `Letters Patent No. 700,484, dated/May, 20, 1902. A v 'Application iiled February l2, 1992.` SerialNo. 93.764. (No model.)

' Be .itknown'that I, HENRY- M-ETTER, a ci ti-n zen,of"the `United States, residing at` Marion, in th'e'county olf-Franklin and-State of Penn-` sylvania, have invented certain new anduseful Improvements in Pump-Heads; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as" will enable others skilled in the art to which v1o it appertains to make and use the same.

This invention has relation to the actuating mechanism of force and lift pumps adapted for manual operation and which are adapted to be connected with asuitabIe motive power, I5 such as a windmill, the invention providing zo the type of pump-operating means embody-k ing a rack-bar and a toothed segment, the

latter usually having a stem to which the handle is bolted or otherwise fastened.V This in` vention combines with the shank of the seg- 25 ment-lugs for confining the ends of plates at taehed to opposite sides of the handle, said plates having inner ribs to enter seats in the sides of the shank, whereby vibration of the handle insures oscillation of the segment 3o necessary to eect reciprocation of the pumprod.

For a full description of the invention and' the merits thereof and also to acquire a knowledge of the details of construction of the-means for eecting the result reference is to be had to the following descriptionand' n 4 -vshown at 17, to receive a portion of the hubs, lw'hereby the lugs are prevented from turning drawings hereto attached.l

While the essential and characteristic fea' tures of the invention are susceptible of modii 4o iication, still the preferred embodiment of Figure 1 is a perspective view of a pump' head embodying the invention. Fig. 2 is a horizontal section through the head about inV line with the axis of the toothed segment and resistance-wheel holding the rack-bar in engagement with said segment. spective view of the segment.

spective view of a-sideplate for the handle. Fig-6 is la ydetail handle.

Corresponding and like parts are referred to in the following description and indicated in all of theviewsofthe drawings by the lsame reference characters.

The top of the pump 1 forms a'base ofthe stand or head and is provided with a stuffingbox 2, through which the pumprod3 Works and to which the rack-bar 4 is attached. Side transverse section offthe v plates 5-are bolted or otherwise secured at their lower ends to the top of the pump'l and areconnected at their upper 4endsA by means or a cap-plate 6, bolted or otherwise fastened thereto and which is apertured in line with the stuffing-box 2 to admit of thev rack-bar 4 working therethrough. The re lsistance-wheel 7` and toothed segment 8 are journaled'inbearings provided at opposite edges of the side plates 5, near their upper ends, said bearings being approximately in the same horizontal plane:` The toothed segmenthas the sides of its 'shank 9 recessed to v y form seats 10 for eoperation with ribs or pro,y jections 11 at theinner' faces of the plates 12,

secured toopposite sides of the handle 13,l so

as to form an interlocking connection of sufficient strength to insure synchronous -movement of the segment and handle when th elatter is oscillated in the operation of the pump. Hubs'lt and journals 15 project from opposite sides of the toothed segment and form an integral part thereof. Lugs 16 are applied to opposite sides of the shank 9, adjacent to the hubs' 14, and their inner ends are notched, as

upon vthe bolt orfastening 18, connecting said 'lugs toeach other and to the shank. The head of the bolt and the `nut applied thereto are countersunk in the lugs, so as not to present The outer ends of the lugs 1G are cut away for a short distance upon their inner sides, as shown at 19,to form spaces to receive the ends of the plates 12. The side walls formed by the cut-away portions 1'9 liare slightly in an outward direction. Hence the spaces 'are a trifle larger at their outer ends, thereby admitting of the readyinserton of IOO the ends of the plates 12 when placing the handle in position and forcing it home.

The handle-plates 12 are similarly constructed and are bolted to opposite sides of the handle 13 and have longitudinal flanges to embrace opposite sides of the handle, so as to produce a firm and stanch joint. The plates 12 have a portion extended beyond the handle, and the extended parts have inner ribs or projections 11 to enter the seats or depressions 10 in the sides of the shank 9. The outer ends the plates are tapered slightly to conform to the inclined side walls of thelugs resulting from the cut-away portions 19,there by facilitating the entrance of said ends into the said spaces. By having the outer sides of the plates 12 and the side walls of the cutaway portions 19 of the lugs inclined a wedging action results when driving the handle home upon the shank 9, thereby preventing any looseness and creating sufficient friction to hold the handle against casual displacement.

'lhe resistance-wheel 7 has integral hubs 20 and journals 2l, the latter obtaining bearings in reinforced parts of the side plates 5. This resistance-wheel is located about opposite the axis of the toothed segment and supports the rack-bar 4 and holds it in engagement with the toothed segment and minimizes the friction.

Having thus described the invention, what is claimed as new is- 1. In pump-operating mechanism, and in combination with a rack-bar connected with the pump-rod, and a toothed segment coperating therewith and having an integral shank with seats in opposite sides, a handle, and plates secured to opposite sides of the `handle and having extended end portions provided upon their inner faces with projecting portions to interlock with the seats in the sides of the aforesaid shank by a sliding movement, said handle being readily detachable from the shank of the toothed segment, substantially as set forth,

2'. In pump-operating mechanism, and in combination with a `rack-bar connected with the pumprod, and atoothed segment having au integral shank, lugs at opposite sides of the said shank and having their outer ends cut away upon their inner sides to form spaces, and a handle having spaced eXtensions to interlock with and embrace opposite sides of said shank and adapted to have the terminal portions of said extensions enter the spaces formed by the cut-away portions of the lugs, substantially as specified.

3. In pumpoperating mechanism, and in combination with the segment for actuating the pump-red provided with a shank, lugs secured to opposite sides of the shank at the inner end thereof and having the sides adjacent to the shank cut away for a short distance from their outer ends, the side walls formed by the cut-away portions being outwardly inclined, a handle, and plates secured to opposite sides of the handle and having extended portions to embrace opposite sides of the aforesaid shank and interlock therewith, the outer sides of the extended parts of the plates being inclined to conform to the inclined side walls of the cut-away portions of the lugs, substantially as set forth.

4. In pump-operating mechanism, and in combination with the segment for actuating the pump-rod having an integral shank, hubs and journals, lugs secured to opposite sides of the shank and having their inner ends recessed to receive a portion of the hubs and having the sides adjacent to the shank cut away for a short distance from their outer ends, a handle, and plates secured to opposite sides of the handle and adapted to interlock with the sides of the shank by a sliding Inovement and adapted to have their ends enter the spaces formed by the cut-away parts of the lugs, substantially as and for the purpose specified. j

5. In pump-operating mechanism, and in combination with the segment for actuating the pum p-rod and having an integral shank and integral hubs and journals, lugs secured to opposite sides of the shank and having their inner ends recessed to receive portions of the hubs and having the sides adjacent to the shank cut away for a short distance from their outer ends, the side walls of the cutaway parts being outwardly inclined, a handle, and plates secured to opposite sides of the handle and having projecting portions to embrace opposite sides of the shank and interlock therewith and having their outer sides inclined to conform to the inclined walls of the cut-away parts of the lugs, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
